Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention mainly relates to an insect repellent sheet for microscopic pests such as mites and mites.

<Conventional technology> Conventionally, the methods for exterminating large numbers of mites and microscopic pests such as mites that have grown on tatami mats and carpets include methods such as directly cleaning and collecting or removing them, or killing them by spraying chemicals, etc. It is used. However, with these methods, the former type of cleaning not only requires a great deal of labor and expense, but also makes it difficult to remove microscopic pests such as mites and mites that are present in the deep parts of thick and complex structures such as tatami mats. If the latter type of chemical is used, there are problems such as the remains of many dead pests, the pests escaping into deeper areas such as tatami mats, or returning to their original location after once escaping to another location. It was hot.

As a method for solving these problems, there are known pest trapping plates in which a sheet material is provided with an adhesive layer containing an attractant, and a net is attached to the adhesive layer. However, these methods were not very effective as even if pests were attracted to the adhesive layer and were captured, they could escape immediately.

<Technical problem of the invention> The technical problem to be solved by the invention is to be able to reliably catch mites or microscopic pests such as mites in a simple way, and to make it impossible for them to escape once they are caught. be.

<Means for solving the technical problems> The technical means taken by the present invention to solve the above problems is to apply an adhesive layer containing an attractant to attract pests on the lower surface of the retaining layer formed in the form of a sheet. established,
A cotton-like nonwoven fabric in the form of a labyrinth in which fibers are irregularly intertwined is provided on the lower surface of the adhesive layer, with a contact prevention member having gaps of an appropriate size interposed therebetween.

<Function> The retaining layer holds the adhesive containing the attractant, and the contact prevention body prevents the cotton-like nonwoven fabric from coming into direct contact with the adhesive layer, thereby increasing the adhesive area of pests to the adhesive layer. I can do it.

When in use, the insect repellent sheet is placed on the floor with its cotton-like nonwoven fabric facing down.

Pests present on the surface of the floor or in the depths thereof are attracted by the attractant in the adhesive layer held in the retaining layer, pass through the maze of cotton-like nonwoven fabric, and move to the adhesive layer. Even if the pests are attached to the adhesive layer or do not reach the adhesive layer, they enter the labyrinth of the cotton-like nonwoven fabric and remain in the nonwoven fabric without being able to return to their original state and live there.

<Effects of the invention> Since the invention is constructed as described above, when in use, the insect repellent sheet can be placed on a floor surface such as a tatami mat or carpet with the cotton-like non-woven fabric facing down, and it can be used not only on the floor surface but also on the floor surface. It attracts pests that exist deep down and traps them in the adhesive layer held in the retention layer, and traps pests that come off the adhesive layer or do not reach the adhesive layer by trapping them in a labyrinth of cotton-like nonwoven fabric. Furthermore, the captured pests can be disposed of as they are together with the insect-proof sheet, making it possible to collect and dispose of the pests simply, reliably, and hygienically.

In addition, even if the cotton-like non-woven fabric is compressed by pressing force, the presence of the contact prevention body between the non-woven fabric and the adhesive layer allows the cotton-like non-woven fabric to completely adhere to the adhesive layer. Therefore, the adhesive area of the adhesive layer for pests can be prevented from being narrowed and kept wide, and the pest-trapping effect of the adhesive layer can be maintained.

Therefore, the intended purpose can be achieved.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

A in the figure is an insect repellent sheet, and this insect repellent sheet A
is composed of a retaining layer 1, an adhesive layer 2 provided on the lower surface of the retaining layer 1, and a cotton-like nonwoven fabric 3 provided on the lower surface of the adhesive layer 2 with a contact prevention body 4 interposed therebetween.

The holding layer 1 is for holding the adhesive layer 2, and may be made of kraft paper (for example, one with a thickness of about 100 to 500 μm), a sheet or film formed of an appropriate synthetic resin to an appropriate thickness, a nonwoven fabric, or a woven fabric. It is constructed using materials such as cloth. The sheets or films used include synthetic resins such as polyethylene, polypropylene, polyvinyl chloride, nylon, cellulose acetate, cellophane, polycarbonate, polyvinylidene chloride, polyvinyl alcohol, and polyester, and the materials for the nonwoven fabrics and woven fabrics include polyethylene, Synthetic resins such as polypropylene, polyester, rayon, acrylic, and nylon, natural fibers such as cotton and wool, or pulp are used. Note that the sheet or film also includes a composite film or composite sheet in which two or more types of polymers are laminated, or a polymer and aluminum foil are laminated. Further, it is more preferable that the holding layer 1 has a suitable strength and is easy to fold due to the material used to form it, a suitable thickness, etc., and also has a structure that makes it easy to attach the adhesive layer 2 to the holding layer 1.

The adhesive layer 2 is for adhering and trapping dust mites and other minute pests, and is made of a material with appropriate adhesive strength, such as acrylic adhesive, natural rubber adhesive, synthetic rubber adhesive (isoprene rubber, etc.). etc.), styrene-isoprene block copolymer adhesive, epoxy adhesive, etc.
It is formed to an appropriate thickness of about 100 μm, and an attractant that attracts the pests is mixed in the layer.

Attractants are composed of ingredients such as fragrances that have the scent of food (tree nuts, confectionery, fish), and tree nut fragrances include alkylpyrazines, cyclopentaviradines, furans (furfural, furucrylic alcohol), etc. ), pyrroles, ketones, etc. Flavoring agents for confectionery include aliphatic aldehydes, aromatic aldehydes, aromatic esters, furans (such as Kurfural), alkylpyrazines, etc. Flavoring agents for fish include fatty acids, Aliphatic amines, aliphatic aldehydes, methyl ketones, phenols, etc. are used. The blending ratio of this attractant is, for example, 0.1 to 3% with respect to the above-mentioned adhesive.
(percent by weight), and the various fragrances mentioned above may be blended alone or in appropriate combinations. These fragrances have a stronger attractant effect on various mites.

A cotton-like nonwoven fabric 3 is adhered to the lower surface of the adhesive layer 2 with a contact preventer 4 interposed therebetween. The cotton-like non-woven fabric 3 is a cotton-like material in which the fibers are irregularly intertwined to form a maze, which induces the habit of the pests to actively enter this maze, and allows the pests to move toward the adhesive layer 2. The purpose is to secure a passage, and the fibers mentioned above in the explanation of the retaining layer 1 are irregularly intertwined to form a labyrinth shape. In this maze, each fiber 3a may be intertwined with each other in an irregularly woven state, or may be intertwined with each other in a state where they are simply overlapped irregularly, and the gaps between adjacent fibers 3a are the ones where the pests are A cotton-like material that can be passed through and is as small as possible is more preferable.

As for the structure of the cotton-like non-woven fabric 3, by using the above-mentioned non-woven fabric, micro pests such as mites and mites can more easily enter into this cotton-like non-woven fabric, and once they have entered, the above-mentioned pests can be released outside. The effect of making it harder to get out is more pronounced. As such a nonwoven fabric, for example, in the case of mites, a cotton-like fabric with a thickness of about 1 to 10 mm and a weight of 40 to 200 g/m ² can be used. The cotton-like nonwoven fabric 3 is then adhered to the lower surface of the contact prevention body 4 adhered to the lower surface of the adhesive layer 2.

The contact prevention body 4 is used to prevent the cotton-like nonwoven fabric 3 from being compressed and deformed due to pressing force, etc., and the fibers 3a from adhering to the adhesive layer 2, thereby reducing the adhesion area of the above-mentioned pests on the adhesive layer 2. It is made of paper, synthetic fiber, etc. so that the contact area with the adhesive layer 2 is small and there is a gap of an appropriate size. As such paper or synthetic fiber,
In the case of mites, for example, a net-like material having a thickness of 10 to 20 .mu.m, or simply a material in which the fibers 4a are arranged in parallel or interdigitated shapes, etc. can be used.

To adhere the cotton-like nonwoven fabric 3 to this contact prevention body 4, use an appropriate adhesive or adhesive;
There are methods such as bonding by fusion using hot melt or the like.

Next, a description will be given of the effect of attracting and trapping microscopic pests such as mites and mites by the cut-shaped insect repellent sheet A. In addition, insect repellent sheet A
The size is appropriately set in consideration of conditions such as the size of the floor B of the tatami mat, carpet, etc. to be used.

In use, as shown in FIG. 2, the insect repellent sheet A is placed on the entire surface of the floor B or at an appropriate position within the necessary range, with the cotton-like nonwoven fabric 2 facing downward.

Microscopic insect pests B such as mites or mites existing on the surface of floor B or in the depths thereof are attracted by the attractant contained in the adhesive layer 2 of insect repellent sheet A and move upward, causing cotton-like Fiber 3 in nonwoven fabric 3
Enter the maze of a. Then, it moves further upwards and reaches the adhesive layer 2, whereby the pest b comes into contact with this adhesive layer 2 and is trapped by the adhesive, making it impossible to move. Furthermore, even if the pest b moves away from the adhesive layer or fails to reach the adhesive layer 2, it may not be able to return to its original position through the maze of fibers 3a in the cotton-like nonwoven fabric 3 and settle there. It becomes impossible to get out of the maze and becomes trapped in the cotton-like nonwoven fabric 3.

As mentioned above, microscopic pests such as mites or mites b.
After the captured insect repellent sheet A is removed from the floor B, it can be appropriately folded with the cotton-like nonwoven fabric 2 inside and disposed of easily and hygienically by means such as incineration.

When using, as shown in Figure 2, insert insect repellent sheet A.
Even if the cotton-like nonwoven fabric 3 is compressed and deformed by being pressed,
Due to the presence of the contact prevention body 4, the fibers 3a of the cotton-like nonwoven fabric 3 do not stick to the adhesive layer 2 over the entire surface, and therefore, the pest b against the adhesive layer 2 is prevented.
The adhesive area can always be widened without narrowing the adhesive area.

In this example, the cotton-like nonwoven fabric 3 is treated with an appropriate binder, such as modified starch, rubber latex, casein, etc. to improve the shape restoring force of the fibers 3a, thereby creating a more stable cotton-like nonwoven fabric. 3 structure can be maintained.

Further, the cotton-like nonwoven fabric 3 may be impregnated with an attractant by an appropriate method such as impregnating and drying so as to attract pests more easily.

Furthermore, the insect repellent sheet A may be printed with a pattern of mats or tatami mats on the surface of the retaining layer 1 to create interior decoration, or may be printed with mats, tatami-like materials, or tatami mats on the retaining layer 1. An insect repellent sheet may be constructed by providing a decorative layer such as a non-woven fabric printed with a pattern or the like, and after use, the decorative layer may be left and only the parts from the retaining layer 1 to the cotton-like non-woven fabric 3 are discarded. good.
